Hi, I am in process of implementing ipv6 firewall so I have given you this link
http://news.softpedia.com/news/Linux...oS-50143.shtml
although 1 am using 2.6.33 - hope it gives you some insight. There seems to be too much information about fragmentation issues to really get a grip on the basic issue.
However, since routers do not re-assemble fragmented ipv6 frames I expect there is the crux of the issue. The fragmentation must be initiated by the sending host and re-assembled by the recipient. Could be there is a problem with many older routers but that is just a a guess. Like I said too much information none of which is consistent.
Good luck
